Furthermore, thedegree of aberration offset can be further described within the limitedrange of 50% to 100% field of view of the formed image. The offset ofthe spherical aberration is expressed as DFS. The offset of the comaaberration is expressed as DFC.

The characteristic diagram of Modulation Transfer Function (MTF) of theoptical image capturing system is utilized to test and assess thecontrast and sharpness of the image formation by the system. Thevertical coordinate axis of the characteristic diagram of modulationtransfer function represents a contrast transfer rate (values are from 0to 1). The horizontal coordinate axis represents a spatial frequency(cycles/mm; lp/mm; line pairs per mm). Theoretically, an ideal opticalimage capturing system may present 100% of the line contrast of aphotographed object. However, the values of the contrast transfer rateat the vertical coordinate axis are less than 1 in actual imagecapturing systems. In addition, in comparison with the central region,it is generally more difficult to achieve a fine recovery in theperipheral region of image formation. The contrast transfer rates(values of MTF) of spatial frequency of 55 cycles/mm at positions of theoptical axis, 0.3 field of view and 0.7 field of view of a visible lightspectrum on the image plane are respectively denoted as MTFE0, MTFE3 andMTFE7. The contrast transfer rates (values of MTF) of spatial frequencyof 110 cycles/mm at the optical axis, 0.3 field of view and 0.7 field ofview on the image plane are respectively denoted as MTFQ0, MTFQ3 andMTFQ7. The contrast transfer rates (values of MTF) of spatial frequencyof 220 cycles/mm at the optical axis, 0.3 field of view and 0.7 field ofview on the image plane are respectively denoted as MTFH0, MTFH3 andMTFH7. The contrast transfer rates (values of MTF) of spatial frequencyof 440 cycles/mm at the optical axis, 0.3 field of view and 0.7 field ofview on the image plane are respectively denoted as MTF0, MTF3 and MTF7.The three fields of view described above represent the center, the innerfield of view and the outer field of view of the lenses. Thus, they maybe utilized to evaluate whether the performance of a specific opticalimage capturing system is excellent. If the design of the optical imagecapturing system of the present disclosure comprises the sensing devicebelow 1.12 micrometers inclusive in correspondence with the pixel size,thus, the quarter spatial frequency, the half spatial frequency (halffrequency) and the full spatial frequency (full frequency) of thecharacteristic diagram of modulation transfer function are respectivelyat least 110 cycles/mm, 220 cycles/mm and 440 cycles/mm.

If an optical image capturing system is simultaneously required tocapture image with infrared spectrum, such as for the purpose of nightvision in the low light source condition, the operation wavelengththereof may be 850 nm or 800 nm. Since the main function of night visionis to recognize silhouette of an object formed in monochrome and shade,the high resolution is not essential, and thus, a spatial frequencywhich is less than 110 cycles/mm may be merely selected for evaluatingwhether the performance of a specific optical image capturing system isexcellent when the optical image capturing system is applied to theinfrared spectrum. When the aforementioned wavelength of 850 nm isfocused on the image plane, the contrast transfer rates (values of MTF)with a spatial frequency of 55 cycles/mm at positions of the opticalaxis, 0.3 field of view and 0.7 field of view on the image plane aredenoted as MTFI0, MTFI3 and MTFI7, respectively. However, since thedifference between infrared wavelength as 850 nm or 800 nm and generalwavelength of visible light is huge, it is pretty hard to design anoptical image capturing system which is capable of focusing on thevisible light and the infrared light (dual-mode) simultaneously whileachieving certain performance respectively.

A half maximumangle of view of the optical image capturing system is HAF. A distanceon the optical axis from an object-side surface of the first lens to theimage plane is HOS. A distance on the optical axis from the object-sidesurface of the first lens to an image-side surface of the sixth lens isInTL. A horizontal distance in parallel with the optical axis from acoordinate point at ½ HEP height on the object-side surface of the firstlens to the image plane is ETL. A horizontal distance in parallel withthe optical axis from a coordinate point at ½ HEP height on theobject-side surface of the first lens to a coordinate point at ½ HEPheight on the image-side surface of the sixth lens is EIN. Conditions asfollows are satisfied: 1.0≤f/HEP≤10.0, 0 deg<HAF≤150 deg and0.2≤EIN/ETL<1.

The thickness of a single lens at height of ½ entrance pupil diameter(HEP) particularly affects the performance in correcting the opticalpath difference between the rays in each field of view and in correctingaberration for the shared region among the fields of view within therange of ½ entrance pupil diameter (HEP). The capability of aberrationcorrection is enhanced when the thickness is greater, but the difficultyin manufacturing such lenses also increases at the same time. Therefore,it is necessary to control the thickness of a single lens at height of ½entrance pupil diameter (HEP), in particular, to control theproportional relationship (ETP/TP) of the thickness (ETP) of the lens atheight of ½ entrance pupil diameter (HEP) to the thickness (TP) of thelens corresponding to the surface on the optical axis. For example, thethickness of the first lens at height of ½ entrance pupil diameter (HEP)is denoted as ETP1. The thickness of the second lens at height of ½entrance pupil diameter (HEP) is denoted as ETP2. The thicknesses ofother lenses are denoted according to a similar pattern. The sum ofaforementioned ETP1 to ETP6 is denoted as SETP. The embodiments ofpresent disclosure may satisfy the following formula: 0.3≤SETP/EIN≤1.

In order to balance the enhancement of the capability of aberrationcorrection and the reduction of the difficulty in manufacturing at thesame time, it is particularly necessary to control the proportionalrelationship (ETP/TP) of the thickness (ETP) of the lens at height of ½entrance pupil diameter (HEP) to the thickness (TP) of the lens on theoptical axis. For example, the thickness of the first lens at height of½ entrance pupil diameter (HEP) is denoted as ETP1. The thickness of thefirst lens on the optical axis is denoted as TP1. Thus, the ratiobetween both of them is ETP1/TP1. The thickness of the second lens atheight of ½ entrance pupil diameter (HEP) is denoted as ETP2. Thethickness of the second lens on the optical axis is denoted as TP2.Thus, the ratio between both of them is ETP2/TP2. The proportionalrelationships of the thicknesses of other lenses in the optical imagecapturing system at height of ½ entrance pupil diameter (HEP) to thethicknesses (TP) of the lenses on the optical axis are denoted accordingto a similar pattern. The embodiments of the present disclosure maysatisfy the following formula: 0.2≤ETP/TP≤3.

A horizontal distance between two adjacent lenses at height of ½entrance pupil diameter (HEP) is denoted as ED. The horizontal distance(ED) described above is parallel with the optical axis of the opticalimage capturing system and particularly affects the performance incorrecting the optical path difference between the rays in each field ofview and in correcting aberration for the shared region among the fieldsof view within the range of ½ entrance pupil diameter (HEP). Thecapability of aberration correction may be enhanced when the horizontaldistance becomes greater, but the difficulty in manufacturing the lensesis also increased and the degree of ‘minimization’ to the length of theoptical image capturing system is also restricted at the same time.Thus, it is essential to control the horizontal distance (ED) betweentwo specific adjacent lenses at height of ½ entrance pupil diameter(HEP).

In order to balance the enhancement of the capability of aberrationcorrection and the reduction of the difficulty for “minimization” to thelength of the optical image capturing system at the same time, it isparticularly necessary to control the proportional relationship (ED/IN)of the horizontal distance (ED) between the two adjacent lenses atheight of ½ entrance pupil diameter (HEP) to the horizontal distance(IN) between the two adjacent lenses on the optical axis. For example,the horizontal distance between the first lens and the second lens atheight of ½ entrance pupil diameter (HEP) is denoted as ED12. Thehorizontal distance between the first lens and the second lens on theoptical axis is denoted as IN12. The ratio between both of them isED12/IN12. The horizontal distance between the second lens and the thirdlens at height of ½ entrance pupil diameter (HEP) is denoted as ED23.The horizontal distance between the second lens and the third lens onthe optical axis is denoted as IN23. The ratio between both of them isED23/IN23. The proportional relationships of the horizontal distancesbetween the other two adjacent lenses in the optical image capturingsystem at height of ½ entrance pupil diameter (HEP) to the horizontaldistances between the two adjacent lenses on the optical axis aredenoted according to a similar pattern.

The horizontal distance in parallel with the optical axis from acoordinate point at the height of ½ HEP on the image-side surface of thesixth lens to the image plane is denoted as EBL. The horizontal distancein parallel with the optical axis from the intersection point of theoptical axis and the image-side surface of the sixth lens to the imageplane is denoted as BL. In order to balance the enhancement of thecapability of aberration correction and the reservation of accommodationspace for other optical elements, the embodiment of the presentdisclosure may satisfy the following formula: 0.2≤EBL/BL<1.1. Theoptical image capturing system may further include a light filteringelement, which is located between the sixth lens and the image plane. Adistance in parallel with the optical axis from a coordinate point atheight of ½ HEP on the image-side surface of the sixth lens to the lightfiltering element is denoted as EIR. A distance in parallel with theoptical axis from an intersection point of the optical axis and theimage-side surface of the sixth lens to the light filtering element isdenoted as PIR. The embodiments of the present disclosure may satisfythe following formula: 0.1≤EIR/PIR≤1.1.

The height of optical system (HOS) may be reduced to achieve theminimization of the optical image capturing system when the absolutevalue of f1 is larger than f6 (|f|>|f6|).

When |f2|+|f3|+|f4|+|f5| and |f1|+|f6| meet the aforementionedconditions, at least one lens among the second lens to the fifth lensmay have a weak positive refractive power or a weak negative refractivepower. The weak refractive power indicates that an absolute value of thefocal length of a specific lens is greater than 10. When at least onelens among the second lens to the fifth in the optical image capturingsystem has the weak positive refractive power, the positive refractivepower of the first lens can be shared by it, such that the unnecessaryaberration will not appear too early. On the contrary, when at least onelens among the second lens to the fifth lens has the weak negativerefractive power, the aberration of the optical image capturing systemcan be slightly corrected.

Besides, the sixth lens may have negative refractive power, and theimage-side surface thereof may be a concave surface. With thisconfiguration, the back focal length of the optical image capturingsystem may be shortened to keep the optical image capturing systemminimized. Moreover, at least one surface of the sixth lens may possessat least one inflection point, which is capable of effectively reducingthe incident angle of the off-axis rays, thereby further correcting theoff-axis aberration.
